Answer:
Θ ≈ 22.6°
Step-by-step explanation:
Using the cosine ratio in the right triangle
cosΘ = 
= 
= 
, thus
Θ = 
( ) ≈ 22.6° ( to the nearest tenth )
Answer:
Add a point at (-1,2) and (0,-1), then connect them
Step-by-step explanation:
The y-intercept is -1 so automatically, you know that (0,-1) is a point. Then since the slope is -3x, one of the points it comes across is (-1,2). Next just connect these lines and make them go further to each side and you're done.
P.S i suggest using a site called desmos if you ever need help with graphing anything ;)
First subtract 3 to both sides to isolate x
2-21-3 = -x
Now calculate what is 2-21-3.
-19-3 = -x
-22 = -x
Now divide both sides to -1 to get x positive.
-22 / -1 = -x / -1
22 = x
So x is equal to 22.
If it is right brainiest please.
5.5 : 30.80 = 7 : x
x = 7 * 30.80 / 5.5 = $39.20
Answer: $39.20
